Neoprene

Neoprene, also known as polychloroprene, is a family of artificial rubbers that ar produced by polymerization of chloroprene. It is the first commercially available man-made rubber. In the early 1900s, the rise of the automobile industry, in particular, had created a strong demand for rubber. Unfortunately, the availability of rubber was limited by shortages and spiraling prices. Furthermore, the particular properties of natural rubber, such as its strike down of resistance to oxygen, oils, and extreme temperatures, restrict its usefulness in authentic applications. These limitations stimulated a search for special-purpose rubber substitutes. Neoprene was invented by scientists in 1930 after Dr. Elmer K. Bolton of DuPont laboratories attended a lecture by professor Julius Arthur Nieuwland, a professor of chemistry at the University of Notre Dame. Nieuwlands research was revolve about on acetylene chemistry, which is the research into a valuable take of compounds in orga nic synthesis, and through his work, he produced divinyl acetylene, a gelatin that firms into an elastic compound similar to rubber when passed over randomness dichloride. After DuPont purchased the patent rights from the university, Wallace Carothers of DuPont took over commercial development of Nieuwlands discovery.

DuPont focused on monovinyl acetylene, which is a certain gas with a deed point of 5ºC, and reacted the substance with hydrogen chloride gas, manufacturing chloroprene. (Picture) This diagram shows the polymer nose of neoprene. It consists of carbon, chlorine and hydrogen atoms bonded together, with a double bond surrounded by the carbon atoms. DuPont first ma rketed the compound in November 1931 under t! he plenteousness name DuPrene, but its ability to be commercialized was hindered by the complex manufacturing process, which left the product with a foul odor. A new process was developed in response to this problem, and the troupe began selling the material to manufacturers. DuPont then worked...If you want to get a full essay, order it on our website: OrderEssay.net
